rTn the drawings, where for the purpose of illustration, are shown preferred embodiments of my invention,A attention is directed first to Figures 1 to 11 and 18, wherein the numerali desig# nates a'casing" or frame including sides'2 I, top 22 y .formed of sheet metal. VThe sides2l have outer recesses 24, formed therein, Figure A3, providing' fianges 2 5, which are secured to side plates 26 by anysuitable means. AThe sides 2l have inner longitudinally thickenedportions Z'Shaving longitudinal'groove's 21 forfreceiving packing or ters' il.'

kheid in'place by pins 15. The strips Tit have 1ongitudinal tongues 'l5 to enter grooves 11. The pins M of each louver unit, Figures 1 2-1'7, are lmounted within the sides 2l ofthe frame, in the identical manner as described vin connection With the rst form of the invention. The bars H have `flat faces l l which slideably engage the packing strips. The pins 44 in the second form of the invention are turned by the identical means as described in connection with the iirst i'orm oi the invention.

The upper and lower ends of the pairs of bars =Elfincluded in the several heads or holders are vertically inclined as, shown at i3. ,The outer layer 6&3 of the inner louver section and the innerv layer 63 oi" ythe outerv louver section terminate atthe tops and bottoms of the bars l'l. When Vthelouvers are closed, thelower ends 1S of the bars 'il engage against the upper inclined end of astop T8' formed upon the frame bottom 23, while vthe inner layer 68 of theinner louver section' overlaps the yinner face of the stop 'I8'.

The outer layer 59 of the inner louver section terminates at its bottom with the bottoms of the bars 'il and terminates at its Atop Withthe tops of the bars 7l, While AtheV companion inner layer SS terminates short of the top oi the bars and,

a pin 88. A groove arrangement 89, similar to pivotally mounted in the frame 2t in the identider |02, and inclined bottoms'. liis,

The innerV layer G8 oithe outer louver section of thel lovvermost unit contactsy with a shoulder 8i) formed upon the stop 76'.v l The plates M of the outerlouver section terminate at their bottoms yWith the bottom of the outer layer t3 and at' their tops with the top of the 4outer layer Se. Pilates' 'l vof the outer louver vsection projectabove the tops of the outer-bars il vandterminate short of the bottomsrof the'outer bars 'l i. The inner and outer plates 'le of each unit are vertically rstagcal manner as described in connection with the first Vtwo forms of the invention and are turned by the identical means described in connection with the rst form of the invention. The intermediate louver section 82,a is held 4Within grooves 90 formed in thebars. 37, while the inner louver section 81a is held within grooves Sl'and the outer louver section 8 3a in grooves Si, covered by plates S2., held in place bythe pins 88. As shown in Figure 15, the inner layer 34 of the inner louver section 8l contacts with a vertical shoulder $33, the inner layer 84 ofthe intermediate louver section 82ev contacts with a shoulder 9&5, and theinner layer 891 of the outer louver section 83a contacts with a shoulder 95,v carried by a stop 9S formed upon the frame bottom 23. The stop 95 has inclined shoulders 3l "and 98. This construction isat the bottom of the frame Zi). As shown inV Figure 15e, the toi). 22 of the frame has a depending` stop 99, providedwith an inner vertical shoulder lill), and intermediate vertical shoulder Hl Landan outer vertical 'shoul- The outer layer 85 of theiinner'louver section 3l contacts with the shoulder itil-the outer layer 85 of the intermediate louver section 82aI contacts with the shoulder IDI, and the outer 4layer 85 oithe'louver section 83a contacts Withthel'shoulder 1&2.v The bars 8l in each pair arevertically stepped, The outer layer of the inner louver section da terminates at its topwith the tops of the 'inner bars l and terminates at their bottoms `With the bottoms of the inner bars 8l. The inner layer te of the inner louver section tls, extends below the bottoms of the inner bars Bland terminate short of Vthe tops of the inner bars tl'. The inner plates S32 terminate short of the tops of the inner gered. :The topil-of the frame is provided with a stop 8i, havingan inclined end vlf,` Aand a depending shoulder 82. The outer layer 69 ofr the innerlouver sectionco-ntactswith the shoulf der 82', and thelouter layer S9 ofthe outer louver section contacts with the outer iaceof the stop 8 l.

When the louver units are in the closed posi tion, they all lie Ain the same plane and ailord a closed dead air space 83. Whenthe louver units areturned from the vertical position, openings are provided between them ior the passage of the air.

' cuter layer 85 extendsat its .top beyond the top of the inner layer 84. ln'feach-louver unit, the `louversections Ele, 82%, andta are carried by heads 8G', including bars 3l,- secured together by bars Bl and project below the bottoms or" the inner bars 8l. The inner plates $2 terminate at their tops and bottoms with the tops and bottoms of the inner layer 8f3 of the inner louver section. In .the intermediatelouver section 82a, theinner layer 34 terminates short at its top with the tops inner ribY it extends from the top of the innerV layer of the intermediate louver section 82?L to the bottom of .this layenwhile the rib |55 extends from the top of the outer-layer B5 of the intenmediate louver section tothe bottom of such outer iayer, and terminates short of the bottom of the inner layer 84., In the outer louver seor tion 83a, the outer plates S2 extend from the top ofy the outer layer 85 to the bottom of the outer layer and terminate short of the bottom of the inner rlayer t'while the rib it extends for the entirewidth of the inner layer 8d, The rib ist extends for the entire Width of the layer 85 of the louver section Sie.

When the louver units are in the closed posi.u tion, their edges produce a stepped interfitting arrangement, and the louver sections are arranged in the sameiplane, and vafford closed dead air spaces 81. When the'louver units are turned from the vertical position, they provide openings for the passage 'of air.

vIn Figures 21- 25 inclusive, I have vshown a modified form of driving means'to turn the louvers shown in Figures 1-3 inclusive. The louefe-10371 7 vers '35 are carried lby the vheads 38 and lthese heads are pivotally connected lwith thejsides 2I ofthe frame `by the pins 44. This `is identical construction as shown in connection with the rst form of the invention.

rIn the present form of the invention, the levers I are dispensed with'and gears or pinions |08 provided. rIhe pinions108 have tubular hubs |09, for receiving the square ends 53 of the pins 44, 'at the right, so that'the pinions and pins turn as aunit. Arranged upon opposite sides ofthe pinions |08 arereciprocatory racks H0, slideably mounted 'in fixed guides III, attached to the side 2|.

Arranged between the 'racks I'I Ais an operating gear or pinion H2, arranged between the two lower pinions H18, and rotatably mounted upon "a stud or shaft H3, carried by a ,plate H4, rigidly secured to 'the Side 2|. The pinion H2 is engaged and driven `by a worm H4', having a tubular hub H5, `the ends of -which are rotatably mounted with'their brackets I I6, rigidly secured to the plate H4. The worm H4 is laterally offset withrespect to'ithepinion I I2, but engages with the teeth of this pinionto drive it. `This arrangement permits the operating shaft I I I to Y clear the racks I'IU. ThisY operating shaft has a square end H8 for insertion within the square bore ofthe tubular V,hub lI I5. Shaft III is hori-f zontal and extends `to the `inner side of the device and'is provided `Awith a 'crank H9 to turn it.

In View of the foregoing description it is obvious that by turning the shaft H1, the pinion `I I 2 Will bev turned, land the racks VI I `movedin opposite directions. ,These racks turn the pinions I08 which are connectedwith the .louvers to open or close them.

Itis to be'und'erstood thatthe forms of my invention herewith shown and described are to be taken as preferred examples of the same and the various changes in the shape size, and arrangement of parts maybe resorted to Without departing from the spirit of 'my invention or the scope of the subjoined claims.
